If uric acid is slightly high in the laboratory indicators of children’s physical examination, it is mainly caused by hyperuricemia, which is caused by the purine metabolism disorder of the body. If it is very high it will cause gout, which will result in redness, swelling, pain and ache in the joints. Therefore, children with high uric acid should control their diet appropriately, and eat less legumes and animal offal, such as pig’s liver and duck’s liver. In addition, apply medication to alleviate the problem, such as applying medication that relieves dampness and clears heat, for example, applying Ermiao Pill and so on.
